Abstract

The invention relates to high-whiteness formaldehyde-free non-ironing cellulose fiber fabric finishing liquid, and application thereof. The cellulose fiber fabric is subjected to non-ironing and whitening one-bath finishing by using a polycarboxylic acid formaldehyde-free non-ironing finishing agent and an acid-resistant type fluorescent whitening agent and by the conventional padding-drying-baking method, and a high-whiteness formaldehyde-free non-ironing finishing product can be obtained. The non-ironing and whitening one-bath finishing method provided by the invention is simple and easy to operate and can be conducted on the existing non-ironing processing equipment of the enterprise; the obtained finishing product has a good non-ironing effect, and the wrinkle recovery angle is more than 265 degrees; and the whiteness is high, the whiteness value can reach 135 and above, and the requirements of the market on the high-whiteness formaldehyde-free non-ironing fabric can be met.

Description

technical field [0001] The invention belongs to the field of fabric finishing liquid and its application, in particular to a formaldehyde-free non-ironing cellulose fiber fabric finishing liquid with high whiteness and its application. Background technique [0002] In recent years, with the improvement of people's awareness of safety and environmental protection, the commonly used N-methylolamide non-ironing finishing agents can no longer meet the requirements of the development of ecological textiles due to the problem of formaldehyde. Researchers at home and abroad have successively studied a wide variety of formaldehyde-free cross-linking agents as non-iron finishing agents, among which polycarboxylic acid-type formaldehyde-free non-ironing finishing agents have the most promising development prospects. [0003] The market demand for high-whiteness textiles is very large, and high-whiteness cellulose fiber fabrics are usually obtained by whitening the original white fabri...
